INSULATING-WRAPPER FOR GROUPED ELECTRICAL CONDUCTORS.

SPECIEIGATION forming part of Letters Patent No. 286,829, dated October 16, 1883, Application filed September I, 1833. (No model.)

'J'l'o all whom, it may concern.-

Be it known that I, JOHN II. KOHMESCHER, of Cincinnati, Hamilton county, Ohio, have in vented a new and useful WVrapper for Grouped Electrical Conductingires, of which the following is a specification.

The invention relates to those grouped conductors whose coverings are connected together, the invention being more particularly designed for use on the terminal wires of a telephone.

My invention consists, essentially, in two or more such tubes cemented together before vulcanization to cause them to adhereto each other 1 throughout their whole length, except for a short distance at their ends, and in re-enforcing the thus joined tubes at their forks by peculiarly-formed Siamese bands.

In the accompanyingdrawings, Figurel isa perspective View of a twin wrapper embodying my invention, the same being shown broken at a part of its lengthto exhibit its form in transverse section. Fig. 2 represents one of my Siamese bands detached.

A A represent two precisely similar pieces of ordinary india-rubber tubing, which, be fore vulcanization, have been united laterally throughout their length, except for a short distance at each end, by means of liquid rubber or other suitable cement. Such junction having been effected, the twin wrapper is vul canized by any customary process.

B 13 represent what I call my Siamese band, which is likewise preferably of vul canized rubber, and so formed, as represented, as to adapt it to embrace, and by so embracing to re-enforce, the said twin wrapper at its places of bifurcation. The bifurcation may be extended farther up the body of the duplex tube by simply slipping the re-enforce temporarily off of the forks and slitting the joining ligature the desired distance by means of a pair of scissors, and then replacing the reenforce. v

I claim as new and of my invention 1. As a new article of manufacture, a vulcanized wrapper for grouped electrical wires, which consists of two or more india-rubber tubes cemented together laterally for the greater part of their lengths, substantially as and for the purpose set forth.

2. A wrapper for a group of electric-wire terminals, which consists of a compound tube, A A, composed of two or more vulcanized india-rubber tubes cemented laterally for the greater part of their lengths, in combination with the separable re-enforce B B, as and for the purposes set forth.

In testimony of which invention I hereunto set my hand.
